DT code

Does applying commit 3c90c55dcde745bed81f6447f24ba96bda43d984 ("drivers: sh: compile drivers/sh/pm_runtime.c if ARCH_SHMOBILE_MULTI") help?

We should have that in our tree (other things don't work). As a note, we did include a debug output showing the clock driver is writing the clock enables for these bits.

The system is also not showing any signs of external aborts, which is indicative of trying to access an IP block when it is not clocked. I will sit down and see if we can debug through this once we've had a look at DMA.
